This exercise scientist says “Yes, especially for men over 35 getting back into the gym.” Here's why...

A personal invitation to get in shape faster—on autopilot—with the world's smartest workout app

"If you want to get in shape fast without a trainer, then this might be the most important invitation you read this year." -Dr. Carl Juneau, PhD

This is me getting my PhD in exercise statistics at the University of Montreal  

Hi. My name is Dr. Carl Juneau. I’m an exercise scientist with a PhD in exercise statistics. I’ve been a coach all my life and a trainer for the Canadian Forces. So far, I’ve helped about 10,000 people get in shape 1-on-1, in group classes, and online.

“You even improve your sex life!”

You improve your self. I believe in self-improvement, and I really believe getting in shape is one of the best ways you can improve. It’s helped me tremendously.

I know: I’ve been a trainer for 18 years. Here are just some of the men and women I’ve helped :

But to make it work for you, your workout needs to start at your level, and improve with you. And the best way to ensure that, is to let a personal trainer guide you, motivate you, and update your plan in real time, as you do it. But trainers are expensive…

Now their results are not typical, and if you really want to get in shape, you’ll need time, knowledge, and motivation. That’s why training is hard. And why so many people fail, especially when they try to do it alone, without a trainer.

So, in 2016, I finished my PhD, I gathered a small team, and we started building this new technology. Our vision was to give you the ability to improve almost as fast as if you had trainer, but for much cheaper.

With this technology, you apply all the latest science and the proven tricks of an experienced trainer, automatically. Under the hood, your training is built around progressive overload. Your program :

  • Starts at your level
  • Gets more challenging as you get in better shape (it adjusts to you)
  • Adds new exercises as you become more experienced, fitter, and stronger
  • Updates in real time when you work out based on your feedback
  • Gives you a challenge when you feel great – Gives you a break when you’re tired

“Lift weights. You’ll look and feel years younger. And this new technology may be the easiest and cheapest way to get there fast.”

“Ever since I got hit by a car in college, I’ve looked for new and better ways to become healthy, lean, and fit. AI is the next frontier in fitness, and if you’re doing any form of weight lifting, you should definitely check this new technology out.”

“90% of people over the age of 35 lose enough muscle every year to burn off an additional 4 pounds of body fat. Don’t let this happen to you. Lift weights. You’ll look and feel years younger. And this new technology may be the easiest and cheapest way to get there fast.”

“This app could get a whole lot of people on track integrating the modern science-based approach to building muscle mass and strength”

“This app could get a whole lot of people on track integrating the modern science-based approach to building muscle mass and strength” This new app looks like a winner. The app figures out sets, reps, volume, loading, and so forth, and does a damn good job of delivering a customized workout based on the individuals progress – or lack there of – using what’s called “Daily Undulating Periodization” or DUP.” “Short of paying a good strength coach, this app could get a whole lot of people on track integrating the modern science-based approach to building muscle mass and strength while reducing the likelihood injuries and removing the guess work. So far, feedback from BrinkZone users of the app has been excellent.” -Will Brink, SWAT Trainer, Magazine Columnist (Over 50 mags in 9 countries), and author of Bodybuilding Revealed “If you are looking for a solid app that helps you to track your workouts, and even offer “advice” on training programs, this new app can help you get in shape faster using artificial intelligence.” Luis Villasenor “Carl and his team have developped an app that allows people to use evidence-based training strategies, and have their training program automatically updated based on their performance & recovery.” Danny Lennon “My colleague Carl Juneau has a neat app out that can help you plan your training and adjusts your training for you.” Mike Israetel “Carl Juneau has worked his socks off to create a high quality AI training app. Highly recommend checking it out if you are looking for a great training app.” Juma Iraki “Carl Juneau has been working hard on his AI training app, one I can definitely support.” Steve Hall “Not everyone can afford personal training – this app is a great way to take the guesswork out of training. One of my favorite parts about the app is the user interface and how many programs there are to choose from.” Brandon Roberts “If you struggle with your workout/training programming, take a look a Carl Juneau’s app – the progress it has made last year is amazing.”

Great for busy, evidence-based doctors and scientists

“I haven’t skipped a workout since I started using it”

“This app creates new workouts automatically that are challenging enough for me to keep building muscle without overtraining. It also keeps me motivated by showing me my progress. I haven’t skipped a workout since I started using it.” -Artin Entezarjou, MD, PhD(s)

“It automates almost all the science”

“Everything I share is backed by referenced scientific research. That’s why I like Dr. Muscle – it automates almost all the relevant science.” -Omar Kaakati, MD
